Headlight's On Alarm? Automatic Headlights?

Greetings!

Is there a way to rig the main door to set off a buzzer when opened if the Headlights are still on with the engine turned off? Similar to how the buzzer goes off when you open the driver door.

Or better yet, make it so the headlights automatically go off?

Thanks!
